Wireless USB host controller support has been removed
from Linux Kernel more than 3 years ago in commit
caa6772d ("Staging: remove wusbcore and UWB from the
kernel tree."), and the associated code in the
snd-usb-audio driver became unused and untested.

If in the future somebody will return WUSB/UWB support
back to the kernel, the snd-usb-audio driver will reject
Wireless USB audio devices at probe stage, and this patch
should be reverted.
